Sybil?

[OriginalGreenGiant]

OR Sibyl...which is apparently a less commonly used name (although it looks a bit odd to me).

Thoughts?

I like Sybil. Classic, easy to say, underused and feminine. Good choice imo.

Also, people would associate the name with your dd, once they know her, rather than an old sitcom, which they think of now as they don't know any others.

A friend of mine named her baby Sibylla. Lovely name.

I like Sybil or Sibyl spellings. Both equally valid

I have a C ecile, and love it; classic French name yet rarely used in the UK. There's also Cyrille...?

Sybil looks right to me, with the Y first.

I also like Sybille and Sybilla.

Sibyl is more correct if you care about that sort of thing. Look it up, it comes from the Greek Sibylla, obviously

Trelawney.

Excellent name.
